MEDIA COMPATIBILITY
The bulk micro-machined transducer features a stainless steel diaphragm with welded construction that
contains no O-rings, which makes them compatible with any gas or liquid that’s compatible with 304L or
316L stainless steel. Some compatible gasses and liquids include refrigerants, glycol, motor oil, diesel,
hydraulic fluid, brake fluid, water, waste water, hydrogen, nitrogen and air.
Installation
LOCATION
Install the sensor in a location where it will not be exposed to extreme temperatures, vibration or shock.
Install the pressure sensor above or on the side of pipes, in a location where liquid will not drip on the unit.
Condensation can potentially build up and run down the harness; position the unit and harness so water
does not pool on the back of the sensor. Do not install the sensor at the end of a long run of pipe.
CONNECTION
The P51 series sensor is available with multiple
external thread sizes, see the Datasheet chart
for more details. Standard pipe fittings and
installation procedures should be used during
installation. Install pipe tape, thread sealant or
other suitable pipe compound when
connecting the sensor to the pressure source or
any of the accessories. For pressure ranges
more than 500 PSI (3447.4 kPa), we recommend
the use of a sealant such as Loctite Hydraulic
Sealant. Do not use excessive amounts of
sealant or you might block the pressure going
into the transducer. Install the device using a
wrench on the hex flats provided. Do not use a
strap wrench on the body. When installing the
sensor, the torque limit will vary, see the Torque
Limits Table for more detail. Do Not over
tighten. Overtightening metal fittings may
cause a slight zero shift. The use of plastic
fittings typically results in no noticeable zero
shift. The torquing effect does not appreciably
affect linearity or sensitivity. In liquid pressure
monitoring applications, air present in the lines
will cause erratic readings, use bleed fittings to
bleed off any air that has been trapped before
transducer installation.
WIRING INSTRUCTIONS
The supply voltage and current required will
vary per unit, see the General Specifications
Table for more details. If you’ve selected a Packard connector make the proper connections to the harness,
then install the P51 Sensor onto the harness.
Note:
Be careful not to kink the vent tube if cutting the 24” PVC wire down or removing all together.
Kinking the clear tube will affect the reference pressure on all PSIG Series Transducers.
4-20 OUTPUT CONNECTIONS
Connect the Power lead (Red) to the plus terminal of the supply voltage. Connect the Return lead (White)

to the plus terminal of the current measuring device (controller). Connect the minus terminal of the
current measuring device to the minus terminal of the supply voltage, and the Shield Wire (Green) should
be connected to the system or earth ground. See
Figure 3
, Current Wiring diagram.
Note:
If the harness has a black wire, do not use it.
